Hi Marius,

I've yet to delve into the actual patches (I intend to do so shortly),
but here's a quick reply to your last message.

That could be better, yes.  They may still be picked up in wrap phases,
but that's a Guix-wide problem (can't tell between native vs regular
inputs on the build side when native compiling).

This is handled for Emacs packages by having a %default-test-flags or
similar that users can cons to... but it's still very too easy to
forget.  Perhaps we should gradually move to most arguments "extending"
the defaults rather than completely overriding them; such an idea was
discussed for example for the #:modules and #:imported-modules arguments
recently.

I'll try to have a quick look now, as I see this hasn't landed yet.
Thank you for picking up this series!
